Canvas Classes · Accepted Answer

Strategy:
 Evaluate the characteristics of H₂-O₂ fuel cells: usage history, efficiency, catalyst types, environmental impact, and classification.

Statements Evaluation:
- A (Spaceship): True. Fuel cells provided water and power for Apollo missions. ✓
- B (Efficiency): False. Fuel cells have high efficiency (~70%), not just 40%. ✗
- C (Catalyst): False. Catalysts are typically Platinum or Palladium, not Aluminum. ✗
- D (Eco-friendly): True. Water is the only product. ✓
- E (Galvanic): True. They
